Hey there - is there such a thing as a 1% zener diode? They all seem to be about 5%. I was looking to make a 10V vref and the best I was able to find was the Digi-Key EDZTE6110BCT-ND, which is accurate to
2.3%. This just strikes me as odd - and makes me wonder if I'm looking in the wrong place or something.I did, however, discover that there are actual 10V vref chips out there - so I'm planning on going with one of those.
